Two brothers carbon fiber, How much?

[CMH]

I didn't want to post this in the for sale section yet because I might be selling them locally first. I'm just trying to figure out how much I should ask for my carbon fiber TB cans and a PC3? I tried looking in the recently sold items and I couldn't find anything really recent for this exhaust. I have a kid here interested in them but if he doesn't buy them I'll post them on here for online sale after I figure out what a reasonable price is.
I would need the stock exhaust from the buyer so I was thinking maybe 500+stock exhaust for the TB exhaust and PC3 package... Thoughts?

This does seem a little low, if I recall I paid almost 600 plus my stock exhaust without the PC3 when I bought them. That was including shipping though.
